The 20 episodes in this four-disc collection include "Quicksilver Murder," in which Cisco and Pancho investigate a crooked prosecutor who robs quicksilver shipments and uses chemical weapons to commit murder. Pancho masquerades as a wealthy man to foil a real estate scam artist in "Mr. X." In "The Epidemic," a ruthless gang heists a shipment of smallpox vaccine and holds it for ransom. A fake newspaper story lures Cisco into a town rife with corruption in "Vendetta."

Based on a character from O. Henry's 1907 short story "The Caballero's Way," this classic Western ran from 1950 to 1956 and was one of the first TV programs filmed in color. Duncan Renaldo stars as Cisco, a kind of Robin Hood of the Old West, and Leo Carillo is his English-mangling sidekick Pancho. Set in 1890's New Mexico, Cisco and Pancho fight corruption and seek justice for the victims of bandits, con men, and cattle rustlers. A total of 156 episodes were shot over seven years and included guest appearances from the likes of Sheb Wooley, Robert Blake, and Denver Pyle.
